The Pathfinder is shown flying low over Rogers Dry Lakebed at Edwards Air Force Base. Its wing is very flexible, while its upper surface is covered with solar cells. While at high altitude, the vehicle was controlled by a remote pilot on the ground, but when the concept is fully developed, a vehicle larger than but similar to Pathfinder may be able to stay aloft for months at a time, without landing and with only sunlight as its "fuel."
